The server is crashing, while I use the Ritual of Overgrowth

I dont know much... but here is the log:

Some stuff I found looking through the log. Don't work on this codebase so I'm no help.

Hope it helps! (Someone working on the code...)

Sorry about that, use this version: https://www.curseforge.com/minecraft/mc-mods/ars-nouveau/files/3310018

You should be able to use it on servers without the clients needing to update, but I have not tested it.
